STAT+: Nutrition experts press White House to release ultra-processed food definition

The petition asks the White House to publish the federal government’s proposed definition of ultra-processed foods. A shared definition could give agencies, researchers, health professionals, and the public a common way to identify these products. The Food is Medicine Institute at Tufts University is presenting the petition to federal officials.

The definition was supposed to be unveiled at an HHS event in August. The announcement was canceled at the last minute. The article links the delay to pressure from major food companies, while the Consumer Brands Association argued that a definition could increase food prices.

More than 80 nutrition researchers and experts signed the petition. Dariush Mozaffarian said HHS wants the definition released before the upcoming midterms. The Office of Management and Budget meeting on Friday could give supporters a chance to push the proposal forward, though industry opposition may still concern the White House.

Ultra-processed foods are generally made through several industrial steps and contain ingredients rarely used in home cooking. Examples can include packaged snacks, sugary drinks, instant meals, and some reconstituted meat products. The category focuses on how a product is formulated, not simply whether it has been heated, frozen, or packaged.

Processing alone does not make a food ultra-processed. Washing vegetables, pasteurizing milk, freezing fruit, or baking bread can preserve food or make it safer. Ultra-processed products often use extracted starches, refined oils, sweeteners, colorings, emulsifiers, or flavorings. These ingredients can change taste, texture, shelf life, and convenience.

The exact boundary remains disputed because classification systems use different rules. The federal proposal discussed in the article could create a common definition in the United States. However, the source does not provide its wording, so its treatment of borderline foods cannot yet be known.

The petition has support from more than 80 nutrition researchers and experts. That figure measures scientific and professional backing for releasing a federal definition. It does not measure how many Americans eat ultra-processed foods or how much of the national diet they represent.

The article supplies no prevalence statistic. Outside this source, U.S. dietary studies commonly estimate that ultra-processed foods provide roughly half, and sometimes more, of Americans’ daily calories. Estimates differ because researchers use different surveys, age groups, years, and classification rules. Household purchasing studies can produce different results from dietary-recall studies.

That uncertainty makes an official definition important for measuring the problem consistently. Without a shared standard, one study may classify a food differently from another. The petition’s supporters want the government to act before the upcoming midterms, but the source does not say whether the proposal will be released or what prevalence figure HHS would use.

HHS is the federal department seeking to release the proposed definition before the upcoming midterms. It planned the August event where the definition would have been announced. The White House is the political center of the dispute because officials must decide whether to publish the proposal amid election pressure and industry objections.

The Office of Management and Budget is scheduled to meet with Tufts University’s Food is Medicine Institute on Friday. The institute will present the petition there. OMB’s review role is stated by the meeting, but the article does not spell out its formal authority or final decision-making process.

The Consumer Brands Association represents food companies and has argued that a proposed definition would raise food prices. Mozaffarian called that claim false and absurd. Its position may make the White House cautious. The article indicates that HHS supports release, but it does not confirm a final decision or timeline beyond the push before the midterms.

A federal definition would establish a shared government standard for identifying ultra-processed foods. That could improve consistency in research, dietary guidance, public communication, and future policy discussions. It could also make the category easier for consumers to recognize, although the article does not promise any particular labeling or regulatory change.

For example, researchers could use the same definition when studying packaged meals, snacks, or drinks. Agencies could compare findings more reliably across years. The key mechanism is standardization: products would be judged against one agreed framework instead of competing definitions. The exact proposal is still unavailable, so its categories and tests cannot be evaluated from this source.

The immediate consequence would be political and informational, not necessarily a new law. HHS wants release before the midterms, while the Consumer Brands Association says the definition could raise food prices. The article does not state that adoption would change prices, require reformulation, impose taxes, or create warning labels.

The best-known alternative is the NOVA system, which groups foods by the extent and purpose of processing. Other approaches focus more on nutrients, ingredients, industrial techniques, or the degree to which a product resembles whole food. These systems can produce different results even when examining the same package.

For example, plain yogurt, whole-grain bread, canned beans, or plant-based meat may be processed but not fit everyone’s idea of ultra-processed. A classification might emphasize additives and industrial formulation. Another might weigh the food’s nutrients, production method, or final structure. The mechanism of disagreement is that “processing” includes many different changes, not one single feature.

The article does not name alternative systems or explain disputed foods. These details come from established nutrition knowledge. The pending federal definition matters because it could select one framework for U.S. policy and research. Until its wording is released, experts cannot know how it will resolve borderline cases.

Industrial processing can extract oils, sugars, and starches, then recombine them with proteins, additives, colors, and flavors. It can also grind, puff, melt, dry, or reshape food. These steps change a product’s structure, texture, shelf life, and convenience. Processing is not automatically harmful; the health effects depend on the food and the overall diet.

A soft packaged snack illustrates the mechanism. Its ingredients may be finely milled and combined with sweeteners, fats, salt, and flavorings. The resulting texture can make it easy to eat quickly, while its concentrated ingredients can increase energy density. Some processing can also reduce or alter fiber and other food structures, affecting digestion and fullness.

These changes may influence health through calorie intake, appetite, blood sugar responses, or exposure to certain additives, though effects vary by product. The article itself does not explain these mechanisms. It does show why a definition matters: researchers need a consistent category to study possible links between industrial foods and health.
